lMPROVEMENT IN WASHBOILERS.

Specification forming part of Letters Patent No. 145,55 8, datedDecember 16, 1873; application filed November 1, 1873.

vTo all whom it may concern:

Be it known that we, OSCAR E. OULVER and LEANDER E. MOSELEY, of EagleBridge, in the county of Rensselaer and State of New York, have inventeda new and useful Improvement in Steam Wash-Boiler, of which thefollowing is a specification:

Figure l is a vertical longitudinal section of our improved steamwash-boiler. Fig. 2 is a vertical cross-section of the same taken on theline 00 m, Fig. 1.

Our invention has for its object to furnish an improved steamwash-boiler, which shall be simple in construction, inexpensive inmanufacture, and reliable and effective in operation, being soconstructed as to operate properly with a moderate fire.

This invention, which relates to certain novel features in that class ofwash-boilers in which the water is distributed upon the clothes to becleansed by steam-pressure, will first be fully described andsubsequently pointed out in the claim.

A is the topof the device, which is made convex or bulging in its middlepart, having about the form of an ordinary wash -boiler cover. The top Ais provided with a downwardly-projecting flange, B, which is secured tosaid cover along its side edges, as shown in V Fig. 2, and at alittledistance from its end edges,

as shown in Fig. 1. The top A is made of such a size as to fit snuglyinto the boiler in which it is to be used, the lower edge of the flangeB resting upon the bottom of said boiler. The end parts of the top Athat project beyond the flange B have a number of holes, a, formed inthem to allow the water to flow down freely into the spaces between theflange B and the ends of the boiler. The end parts of the flange B havea number of holes, 1), formed in them to allow the water to pass throughfreely. O are partitions placed a little distance from the end parts ofthe device, and with their upper parts inclined inward. The side edgesof the partition G are attached to the flange l3, and

their upper edges are attached to the top A. In the upper part of thepartitions O are formed large slots or openings, to allow the water topass through, which openings are covered upon the inner sides of' thepartitions G with the plates or valves D, which are hinged at theiredges to said partitions. By this construction the valves D, when leftfree, will drop inward by their own weight. E are stops attached to theflange B for the valves D to drop against, to prevent them from droppingtoolow. In the center of the top A is formed a hole in which is securedthe lower end of a tube, F, which may be straight or tapering, and toits upper end is attached a semicircular tube, G,

which may be made circular or rectangular in its cross-section, as maybe desired. The latter construction I prefer, as it spreads the waterand steam more evenly over the clothes. By this construction, as thesteam begins to form, the first effect is to close the valves D andprevent the water and steam from passing toward the ends of the device.

As the formation of steam continues, the steam and water pass up throughthe tube F,

and are discharged upon the clothes. The water percolates through theclothes, flows down through the holes a in the top A, flows through theholes I) in the flange B, presses open the valves D, and flows into thecentral space of the device, to be again heated and discharged throughthe tube F, thus establishing a circulation.

This arrangement of the valves D prevents the back-flow of the water,and at the same time allows the free inflow of the water. The valves D,opening from their upper edges, allow a slight inward pressure to openthem, thus preventing any undue pressure of steam.

Having thus described our invention, we

claim as new and desire to secure by Letters Patent- In combination withthe water circulating and distributing attachment A B F G of awash-boiler, the valves D hinged at their lower ends to inclinedpartition-plates 0, having passages or openings 0, and combined withsuitable stops E for limiting the opening movement of the valves, as andfor the purpose set forth.
